Although david answered this I want to add a supplemental opinion.

Technically, yes, you can run with 10,000 users. With that said however, 
for practical purposes, you would suffer performance issues at that 
level which may not be solved just by using a faster box. The processing 
of pppoe control frames is single threaded and is hindered by linear 
table lookups, which works well up to moderately busy networks in terms 
of the rate of connecting/disconnecting sessions, but could potentially 
stall out and reject users or drop requests once the magic threshold is 
reached. I would recommend using vlans to segment your users and run 
multiple rp-pppoe instances instead with an eye of keeping it to a 
maximum of say 1000 users per instance instead, which would greatly 
limit this effect.
