I would have thought that packet based LB would require some form of
multilink ppp/lacp between you and the internet service provider to work
properly. 

Some ISPs here in the UK do offer that facility as an option on their DSL
services. 

IIRC one provides a PC + DSL cards + custom Linux build which does the
multilink goodness over the multiple lines back to their head end. 

Outbound, flow based connectivity over multiple egress points isn't that
hard to do.
