Thanks apmuthu, your patches has been integrated with current FA version.
I guess nightly build is not necessary to be in touch with newest FA version. Everybody interested can clone FA hg repo and have all the changes tracked online. There is also not so much fixes included daily, and we do make new minor release after every important or security fix.
There is no publcly available pro version (whatever you mean) now, payroll module is in really alpha stage, so unfortunatelly it is not usable yet.
There is no official comparision page for FA & webERP I know about.
Yes, we should provide instructions about COA extraction, or even implement some extraction utility in any next FA version.
Regarding OpenVZA, I have no openvz enabled box avaialble just now, so I cant check and publish the template. But this is interesting option for the near future.
