   Vincent,   
      
   VB-Oracle can be very stable but like previous posters mentioned, you   
   need a very tightly managed desktop.  We have VB-Oracle apps running   
   supporting 3500 users and the desktop is managed by SMS for a "standard"   
   client and to auto-push deployments.  If you don't have a tool, it'll be   
   difficult to do deployments and DLL management.   
      
   Regarding using Citrix,  the network footprint is about 24k per user so   
   you need to make sure you have the bandwidth.  Also, latency values can   
   kill you if they're over 100ms.  A GUI-driven app with bad latency will   
   drive your users absolutely crazy or else they learn the accelerator   
   keys REAL quick.
