Yes, it is worth a wiki page, but your information in the first post doesn't contain many details. I suggest a table with the following format:

ISP (and the network provider; the corporation who owns the network) - max down/up speed - data limit or FUP - price - phone only or anything goes - AUP restrictions (e.g. no VoIP allowed) - misc (e.g. caps to 1 kB/sec after 1 GB)

Example: XS4All (KPN) - 768/384 - 1 GB - 30 EUR/month - anything goes/laptop - (empty) - (empty)

On bottom or seperate page, user experiences.
