Thanks so far Andrew and Ricardo, I will read through all of the
information and try what's suggested there!

Using a (e.g.) 100Mbit connection, I would like to limit a set of hosts

Would that be possible with tc? Do I have to create one queue per host
with a limit of 1MBit/s and a match filter for the client's ip address?
Yes, I'm pretty sure you'll have to create a separate leaf class for
each IP address.
If that is a the case, how many queues can I create? Would it impose a
problem for a system to handle e.g. 500 or even 10.000 queues at the
same time?
It depends how you're doing the matching. If you've got that many queues
then you'll probably need to use tc hash matching. There was a lengthy
thread on the netfilter mailing list that touched on this a while ago:

You will probably find the replies from Marek Kierdelewicz the most
useful.
