CONFIG_IP_ROUTE_MULTIPATH as alternative to EQL ?

I am interested in hearing from anyone who has enabled
CONFIG_IP_ROUTE_MULTIPATH in their configuration, possibly as an alternative
to EQL driver for seamless bundling of bandwidths of multiple serial lines.

We have one ISDN, and two dialup links between two buildings with latest
versions of linux (actually 2.1.101) running on the systems. I am about
to experiment EQL and also MULTIPATH options. I am preferring the latter
since it will allow VJ compression to be enabled on PPP links.

How can we use MULTIPATH option for links which are not equal in capacity?
Can starvation be taken care of? My current understanding is that since
there is no mechanism to provide this info, it is not taken care of.
I feel that the routing should be dependent upon number of packets waiting
to be sent on line on each of the ppp devices.

I am interested in getting any pointers (and standards) regarding
algo's for implementation of MULTIPATH options.
