A *very* bad idea for security reasons.  If anyone can write to the 
app, they could replace it with an arbitrary program, including one 
which could damage the system (delete files, etc.), while leaving the 
icon, etc. intact.  Some unsuspecting user with more privileges than 
them could then run the program, which has been replaced with nasty 
code, damaging the system, their files, etc.

Another issue here is that being able to write to the apps means 
allowing some as-yet-unwritten virus to infect them.  If a user can't 
write to them. then neither can a virus running under their account...

In a slightly less hostile sense, being able to write to the app means 
being able to ruin it unintentionally as well.
