Does your app need the server?  SOLO apps are statically compiled so  
eliminate any waiting for compilation.

You could write a small Flash or SOLO app that gets replaced by your  
app when it is loaded, but you really shouldn't need to if you either  
convert your app to SOLO or pre-fill the server cache (see below).

You want to look at the build system for a distribution.  This uses a  
script with curl or wget to prefetch apps and then saves the  
compiler, data, etc. caches in the servlet so there is no compilation  
in your distributed app.
