You didn't tell if you use pptp, but I think you use pptp.

ppp interface in this case is a peusdo network interface, under it there
is IP connection between client and server. So your control the ip
connection's rate, and then you can control the ppp interface.

So if you want fairness amongst these interfaces, you can either enforce
fairness on connection ( 1 client only has 1 ppp connection) or enforce
fairness on host (1 client may have multiple ppp connection but you take
the client as one)

I am not familiar with ESFQ. In my test, SFQ doesn't provide good
fairness. ESFQ should have some improvement, I think.

Any good implemented fair queue can achieve your goal.
