[imp] Allowing users to choose IMP or MIMP

[Kevin Konowalec]

Horde: 3.1.4
Imp: H3 (4.1.4)
Mimp: H3 (1.0.1)
Turba: H3 (2.1.4)

What would be the best way to allow users to select MIMP or IMP as  
their mail client on login?  We have a few users with visual  
disabilities and they use page readers to read web pages.  The  
readers don't work very well with IMP so I'd like to allow them to  
use MIMP for the text-only, no frills simplicity of it.  I'd rather  
not have to run a duplicate instance of horde on another machine  
dedicated to the handful of users who need this if I can avoid it.   
I'd be very happy if you could just choose one or the other from the  
login page - is that possible?

Thanks

Kevin
