thanks kevin, By the way
my issue is related to centralised architecture. hosting rpt files on the client machine is the most easiest way.
as far as benefits of centralised host for rpt's,
the easy update will be the most cumbersome one when u have many users and u have more trouble when some of them dont update their version of rpt files.
apart from that there are LICENSING ISSUES and lot of money involved depending upon no. of users.
WELL the question is still open for other experts
