If there is anything to grip onto then try some vice grips to lock on and twist it out
 
If you can grip something or say wedge a flat head screwdriver in and get it going that would probably be your better option.

After this there are a few options but most will require not specialist tools but things you probably will not have around. Just before I get to that though a hacksaw blade that can make a slot for a flathead screwdriver works well a lot of the time but if it is a recessed screw that is somewhat more difficult, you can try making a slot with a drill but that tends to work better if you have skills with such a tool.

If the head is messed up then you can drill down and get a screw extraction kit. Most people will have screwdrivers, spanners and various socket sets but rarely do I find these in the average toolbox.

For the size you want you can probably pick up a kit for next to nothing or if you are friendly with a mechanic they will almost invariably have set of these.

Option 2 but one I usually save for mechanical grade bolts (things that take serious load as opposed to the pencil thick things I imagine you are looking at right now) is weld/braze/solder something in there and then twist that out.

After this is resolved you might want to consider getting either a tbar allen key set or something with a proper ball end like http://www.pearsestreethardware.com/images/allen%20keys1.jpg - saves a lot of cam out and messed up bolt heads.

Everything depends on whether you have a replacement screw or not. Try the vice grips as suggested, if that fails, fill up the stripped portion with a Locktite-type glue, place the original key in the socket and wait until it sets, then try unscrewing it. If all else fails, drill through the screw.

To make things easier for yourself, you could use WD-40 on the screw to attempt penetrating the threads.
 
i work on bikes as a hobby. to remove 5 an 6mm alanhead screws i'll either use a drill, a screw removal kit, or a owl hole punch. depending on how deep it is, you can use a drill to start threads on the top of the stripped part, then use either a screw removal kit (sears sells a nice craftsman one). the other method is to just use a second screw, feed it into the threads you created until you can make it any tighter and then back it out. both of these methods do not always work, it depends on the type of drill, your ability to keep it perfectly straight, how deep you can drill to make threads, etc. the other method i use is a owl punch and a hammer. i hammer a straight line into the screw and then use a regular screw driver to take it out.

these work for me because alanhead screws on bikes are never tightened to their fullest. on a set of rollerblades that might not be the case.
