I know where you're going with that but why? You can use WPA on a
WRT54G as long as your clients support it and given a strong password,
that's going to suit pretty much all home users.

IPSec has limitations too, how were you planning on authenticating?
Which EAP type were you going to use? EAP-MD5 for example is easily
dictionary crackable for example.
