Currently we have no solution. Thats not good either :-)
If this solution requires no changes to the code, makes updates easy and
incurs no overhead for the common case(single PPPD)...
Slightly increased code size(only PPPD code is duplicated, not the rest
of eCos) and probably not very much more ram usage.
Perhaps you know something I don't, but it seems like a very economical
solution.
Now, the next question is whether it will work out of the box...
