what have your customers asked for exactly?

but rather than throwing your LVM at Linux (and having 2 different
LVM implementations - bad), why not re-examine your customers needs
and work with current LVM using your experience/concepts from IBM LVM
to develop an architecture that does meet those needs. An
architecture perhaps different from current-LVM/IBM-LVM but still
drawing on that experience.
i take it adapting IBM's LVM to linux will not be straight forward,
so the choices are:
1. port IBM LVM -> 2 seperate LVM implementations.
2. use current LVM with only slight improvements (possibly not
meeting your customer's needs)
3. work with Heinz and the rest of the linux community to build a new
LVM architecture, taking the best concepts from both IBM and Heinz
LVM to build a new LVM architecture superior to all the rest.
whatever you do, i think option 1. is the least desirable.
