have you ever used bytecoin?
No --- and I personally don't quite care about anon coins in general.
The only real deal are the CryptoNote devs --- unlike Monero devs, who're posting on BCT all day and don't get anything done
Granted, there are also interesting coins that are built on CryptoNote, ie. DigitalNote. Monero is just so far behind. IMHO it's not noteworthy.

Do they have a database implementation or is the blockchain entirely in memory?
i'm seriously curious because I don't want to run the software to find out.
