Huh?!?! - Until such time as Desktop apps are killed off completely (don't see that happening anytime soon), I actually prefer to recommend Citrix or Terminal Server based solutions than purely Web-based.
Maybe David's problem was actually using the term "Citrix" instead of the more "MS-friendly" Terminal Server. VFP continually gets updated in service releases to better support Terminal Server applications(recall the NOBITMAP setting in SP3 for VFP 6). In fact, in one newsgroup, one of the fastest suggested ways to build a "mobile" app for the PocketPC was NOT to use SQL Server for PocketPC, etc but rather to build a Terminal Server (read: CITRIX-like) application and connect to it using the PocketPC's Terminal Server client. The only caution was "keep your screens really small".
It's the "MS response" that really hurts the community. Promoting VFP with ASP.Net is great for all those bleeding edge developers (and yes, I know it hurts to say it but for most people ASP.Net is still a little too bleeding edge for many companies - note that not even MS bCentral allows SOAP access on their .Net services - wonder why not?).
The fact is that EVERY developer needs to be told of workable solutions. Citrix and Terminal Servers represent GREAT Solutions for companies who have remote needs and WORKING desktop applications. VFP is not only ideally suited in these environments - it kicks serious butt when it comes to performance! Why? Because the application actually runs LOCALLY instead of being on a network.
Other reasons to consider Citrix/Terminal Server solutions:
1. It's easier to support - you can shadow other users, and easily disconnect users when connected.
2. Single point of access - easier to track errors, provide updates and more.
3. Single type of workstation - easier to manage. Hell, even better than trying to deal with multiple browsers
4. You can FIND many companies willing to HOST TS servers for you - yes, they may charge for it but will provide 24/7/365 uptime with various guarantees (check out http://www.meganetserve.com)
If you have never considered using Terminal Server as a remote solution for your apps, I strongly recommend it. AND it's getting easier and better. Don't be fooled by Microsoft's response - VFP does work well under Citrix and is always being improved to work better because of it. (just don't mention Citrix in the same breath <bg>)
