Looks like a good time to upgrade to 951 brakes.

1. Remove the caliper from the car and plug the open brake line.
2. Apply PB Blaster around the broken screw.
3. Drill out the center of the screw - use a left-twist drill if you have one.
4. Heat the area around the screw, but not too much.
5. Gently tap an easyout into the hole.
6. Twist on the easyout. It won't budge.
7. Twist harder. Break the easyout.
8. Get mad - throw caliper across the garage. Try not to hit anything valuable.
9. Go to the parts store to order another caliper. They won't have one in stock.
10. Search online for a rebuilt replacement caliper. Order one. Wait a week for it.
11. Receive new caliper - curse at the crappy job they did replacing the bleed screw.
12. Install it anyway. You've been without the car for a week and you just want to drive it.
13. Repeat for the other 3 wheels.

If you can remove the broken bleeder screw, you can get a replacement at the local auto parts store so that you don't have to wait for shipping. Just bring an old one in so they can match the thread.

Hahaha. Rockfan, how do you know this? 
Anyway, I'd be leary of drilling or using an easy out on a caliper, as if you get any shavings in the caliper that eventually make it back to the master, they will probably reek havoc on the seals.

bigal,
I upgraded my 944S to 951 speca a few years ago. I'm sure I have 4 calipers sitting in a box somewhere. I'll try to find them this weekend - if you join Rennlist, I'll send you one of the for free to replace the broken one.
If you break the other 3, I promise (rennlist honor) to let the other 3 go VERY cheap.......
Oh sh*t, your in Scotland. If you think shipping won't be too bad, the offer still stands. Let me know.
This is assuming I can find the damn things.

as you said i am in Scotland so due to the cost of shipping i would only be interested in taking the set of 4 (only one shipping cost)
what you want for them including shipping

remove caliper
strip it down
drill then tap out hole
fit new seals(think you get a seal kit)but not sure
refit caliper
next do the other three

You can do that. Try the easyout first. It's important to drill a bigger hole as that will weaken the bond the old screw has on the caliper. If you can't get it out, you can drill the whole thing out and install a repair kit. (Step 11 in my original post) It looks like this. Do you have access to a drillpress? It's much easier to keep everything straight and centered with one.
As far as the other three, I haven't tried this but I hear it works. No promises. Remove any loose rust around the bleed screw with a wire brush. Heat the caliper, but not red hot. Touch some paraffin wax to the bleed screw and it will wick down into the space between the threads. Let it cool, then try (carefully) to remove the screw. Let me know if it actually works.

They are fairly common, most good auto supply stores should have them, as they are generic and fit any caliper that you can drill a hole in. Last time I bought one it was from a store for farm equipment and large trucks. They come in more than one size - get the smallest one they have.
