This is fairly interesting -- I never thought bba-groups could be used 
as a pppoe client.

This topic came up before at least twice.

http://puck.nether.net/pipermail/cisco-nsp/2005-January/016094.html

It was ignored at least once.

I agree with you, no pppoe-client support on subinterfaces is a gross 
omission, however its a fairly common one -- juniper ssg netscreen share 
it for example IIRC.

As you say, linux has no such limitation.
