that is an expensive route for crystal reports server. i have put crystal reports server on the same box as evo. i am referring to the server version of crystal reports which is not the devoper version. it's more for just managing reports and user thru a web channel.
cheaper to use a crystal report viewer like CVIEW from Chelsea Technolgies in NZ. 5 user license is $200. then you develop the report on your machine. put report on server, and users have Cview on their PC and can open / run reports.

well, at least the nice thing is that all users have a web browser, and you have central management. but there is no problem with performance interference as far as that goes.
