1-5 common for a both (to a greater or lesser extent),
but Lb _demand_ that TRACE32 installed on host and
may communicate _only_ with TRACE32. And, if your bumped
with problems with TRACE32 (_host software_, not hardware)
at the middle of annual subscription, your _must_ prolonger
subscription (not for free of charge) since LB released fixed
TRACE32 when your current subscription will be closed.
We bumped with such situation when worked with Hitachi (Renesas)
SH7751 family. TRACE32 know _nothing_ about new revision (7751R),
and refuse to work at all. For a defeated of Lb,
I could say that I don't know what Abatron offer in this situation,
and this situation was 3 years ago.

I already point to it (scalable etc)

Since protocol _closed_ and patented (I think).
