Multiple and severe.

No, it's not "hijacking" per se, but if you are not experienced and
skilled enough to handle this (and given you are asking these questions,
I gather you are not) PLEASE DON'T, for the sake of the company you plan
to do this for (or against?).

That is always true, any open port is a threat.
Skype doesn't use predefined TCP/UDP ports for its traffic, you can't
"open ports for Skype". It's made to self-adapt and cross routers, NAT
devices and firewalls. In fact, you can't STOP it from crossing your
firewall: you need DPI (Deep Packet Inspection) to determine that that
specific traffic IS from Skype, it's on a different ISO/OSI level than
most firewalls work onto.
Again, your level of knowledge is consistently low so I won't recommend
you to adventure in such minefields.

> Any other gotchas?

Skype is NOT an application that should run though a corporate network.
It's a simple basic tool to allow private individuals to have basic
conversations through their PCs.

If you are after business grade communication, Skype is NOT suitable.
