[Building Sakai] Idea: Change the GUID generator for Sakai

[Charles Severance]

Hi all,

I am wondering if we should just change the guid generator for Sakai to generate something smaller.  Out GUIDs are 

8923c6aa-794f-43f0-8ea2-dc6f96556d6b

Things like YouTube have much more dense guids like 

XhcsnjHjIWc

I don't know if there are reliable and yet short guids that use things like upper and lower case letters, etc.  Our GUIDs are HEX - not the densest.

I am not talking about any conversion of old GUIDs - just new ones.

What do folks think...
