Linking co-ax and RJ-45 sectors

I have a home network which is mostly RJ-45 but has one *long* co-ax
link to a computer right at the other end of our (large) house. At
present I have an old 10Mb/s hub dedicated solely to the job of
converting from RJ-45 to co-ax.

I'd really rather like to pension off this hub (to save space
basically). So, what alternatives do I have:-

I have a number of devices (D-Link DE-530 card, ISDN router and a
print server) which have both RJ-45 and BNC connectors, is there
*any* chance that these can be used to interconnect the two?
(I suspect not but I may as well ask!)

Are there any cheap(ish) 10/100Mb/s switches which have a BNC
connector as well as RJ-45? (I couldn't find any)

Can I stick a card with a BNC connector (e.g. the above D-Link
one) so that one computer has two cards and interconnect that way?
I'm pretty sure I can do this but it makes the routing complex as
I think it requires two subnets.

No chance at all.

Coax ethernet is so far out of date that nobody bothers to cater for it
any more.

I suspect you can do this just by using the network bridging facility in
Windows XP, but I'm not thinking all that clearly ATM.

If it is purely to save space, buy a small 10Mbps minihub with 4 RJ45
and one coax connector instead of the, presumably big, existing hub.
They are quite cheap; even cheaper on Ebay.

How long is the long link? If less than 100m, you can use RJ45 cable,
unless it's too much hassle to change.

Yes, I'm sort of thinking of this last approach, it's well under 100
metres. It's probably 30 or 40 metres as the cable runs and I could
use the old coax cable to pull the RJ-45 through. I might even
'invest' in a drum of UTP, some RJ-45 plugs and a crimp tool. I could
then make all my leads exactly the lengths I want (subject to minimum
and maximum lengths of course).

Oh they do, it is just that now it is a specialised market and hence has
prices to suite. You also need to know where to look. In particular hubs
with BNC connectors are increasingly hard to come by at reasonable prices.

There are plenty of places that are still wired with coax and rewiring
with Cat5/6 is not an option through either cost or problems with building
infrastructure (think asbestos).

This hub might be a fair bit smaller than the one you're using ATM:

No need - we'll custom-make Cat 5e or Cat 6 cables to whatever length
you require (to nearest 10cm).
