1) It appears to be working fine, although it is very down and dirty. If you want it to look great, then you need to do a lot of work on it. On 3.6.8PL2, I don't have any admin hash mismatch errors. Then again, maybe I'm not looking in the right place.
2) Not really. Because of the lack of features (like folders/filters) and the lack of the catchall address functionality it's less intensive than something else like vbms.
The only way I can see it being intensive is if you had it checking for e-mails on every page you view (like an e-mail notification underneath the PM notification).
