Is the Usenet Gateway mod suitable for a shared server?

[boatdesign]

I asked this question a few days ago and one person was nice enough to share their experience running the mod via email, but I wanted to get some more feedback and specifics. The original question got lost in the 17 page thread (original: http://vbulletin.com/forum/showthread.php?threadid=7100) so I thought I would break it off and start a new thread to see if this is something I could install on a shared server:

I am very excited about the possiblity of integrating 2 usenet newgroups with my vBulletin forums, but I'm worried about doing anything which might endanger my hosting account.

1.) Can this script be run on a virtual/shared host? (300 other hosting accounts per RH Linux server, P3 800, 1 GB Ram)
Is anyone running this on a shared host, or is it for dedicated servers only?

2.) What kind of server resources would be required if I was looking at including 2 usenet groups which currently have 100 messages per day max?

3.) What happens if connection to the news server hangs? (lingering processes?)

Also, I am a little worried about the possibility of being targeted by a spammer who could use my forums to spam usenet and thus get my hosting account suspended.

4.) Is there any type of post rate limiter designed in?

5.) Is there an option to allow only moderated posts to usenet (or maybe an option to have them appear in the forum before being approved for posting to usenet?)

Thanks very much - this is a fantastic option. I just hope that I will be able to use it.

And thanks again for any feedback... just want to make sure I won't endanger my hosting account by installing this.
