This is precisely what we are doing on the main network. We just want to keep the general browsing traffic separated.

I am hoping that this will eventually become a moot point for this particular installation, but as it is, the cable modem is $50/month for 15 Mb/s, and adding 15 Mb/s to the main network would cost around $3,000/month. It is really hard to justify.
If we could BGP via the cable modem, that would be great, but they won't allow it :)
