Probably not, but it depends.

If you're using a challenge-response auth method (EAP, for 802.1x 
wireless or wired; CHAP for VPN/dialup/ADSL) then no. It's impossible.

If you're using PAP or similar, then you could probably write a script 
to cache them, or use rlm_caching - see raddb/experimental.conf for the 
"caching" module definition.
