I would use iptables for this. I hope your mldonkey is running with its
own userid (perhaps mldonkey). With iptables you can check all traffic
created by this user:

iptables -N mldonkey_count
iptables -A mldonkey_count -i ppp0 -m owner --uid-owner 524 -j RETURN
iptables -A mldonkey_count -o ppp0 -m owner --uid-owner 524 -j RETURN

iptables -I INPUT -j mldonkey_count
iptables -I OUTPUT -j mldonkey_count

You get a new chain with 2 rules in it. The first one counts incoming
bytes, the second one outgoing.
This is pure theory and written from scratch for this mail and I don't
know if -m owner works with incoming packets.
You need to change the uid (524) and the interface (ppp0) to the one you use.


But, I agree, it would be nice. But it won't be precise, because you
forgot the overhead (tcp-header, and perhaps pppoe-header too) which is
not created by mldonkey itself.
