This topic seems to come up now and then.  The idea is actually pretty

1) Most commercial satellite operators don't want to sacrifice space
for an amateur payload.  They'd rather use any excess launch mass for
station keeping fuel.

2) Risk:  The risks of carrying a third-party payload can be mitigated
and well understood, but this takes time, effort and money.

3) Possible interference issues from the payload.

4) Power:  This can be budgeted for, but again, there are time, cost
and money issues associated with a parasitic payload.
