XenDesktop is often overused where a XenApp published desktop will do, but implemented badly....users get set against it. If you can afford the XenDesktop licensing, it's good, but the 1:1 nature of the machines means it has a lot of overhead in resource and management.
If you have any specific issues with XenApp feel free to post them to the list, there's quite a bit of Citrix knowledge on here. Cheers, JR Sent from my (new!)

Responses below: >>Wouldn't something like Citrix XenApp offload the performance hit onto the local network for your remote users? Good suggestion. We're actually already using it(have been for 10+ years), but end-users hate it. I might end up trying something like XenDesktop and see if they like that better just for remote access.... >>It is, however, something that WAN accelerators were designed to help mitigate. I saw that Riverbed has a mobile client which sounds interesting. >>So normally the SQL traffic is between the users desktop and the sql backend? Yeah for some of the apps the traffic from the workstation can easily hit 100megs doing a normal operation or query. >>A VPN is just a network link. Nothing more, nothing less. Think of it like a really long Ethernet cable. Very good point. I'm over thinking it. I think the end-users have psyched me out by keep saying all other companies have VPNs. It seems like using a VPN w/o something like RDP or Citrix is only useful for simple apps like outlook/word/excel/etc. Summary: Sounds like a VPN is what it is, and something like Citrix is the current best solution for chatty apps...
