oh, ya, I hadn't seen that class but the idea is similar. I guess because I was using the app not database, I put in an instance number or something about the host/port or something.
this brings me to my next question -- how about those modern looking bit.ly type id's ? seems like you can take the key or counter value and mod your way through a set of characters and build up a super-short id - no? I have ERRest doing my work right now, but I'll be wanting to email URLs to the web app and figured I'd prefer not to show id's but rather could use a counter like bit.ly urls and I haven't yet looked into that.
