Forums mIRC Help Password or .ini file encryption?

I run a system where the users want to use mIRC instead of MS Comic Chat to connect to an Exchange 2000 Chat community. The problem is, the mIRC client stores the user's account password in clear text in a non-encrypted .ini file. Is there a way to encrypt either the password (contained in the host= variable) or the entire .ini file (mirc.ini)?
