Porting efforts: estimates?

[Tom Chmara]

The question has been raised by some of our exploratory groups that we should
determine the amount of effort we use in maintaining some of our non-telecom
OSes (i.e. proprietary OSes without real real-time requirements) vs the amount
we would require to port and maintain a more industry-standard (half :-) here)
OS like UNIX.  As I have network access, I got elected to ask.  Here goes:
We have the information regarding our own OS efforts; what I
need help with is the time/effort (person-years of work) required to:
	- port either BSD or SysV to a new platform, and
	- port new releases to this platform.

Anyone willing to hazard some numbers?

	Thanks...

As is more-or-less standard practise, I will summarize to the net...
