Congrats Tom for rising to the challenge ;)
istm that a brute force hack such as is being suggested should be left
as an exercise for the reader.
These "table links" seem to controvert the ability for a RDBMS to mix
and match tables in ways which are not hardcoded beforehand.
Regardless of whether "there exist some real servers that offer such
features I am talking", a departure from the relation model in a
relational database is likely to lead to undesireable constraints and
restrictions in our future development.
If they are a good idea, you might be able to implement and prove them
using an embedded language and the SPI facilities.
Just the usual $.02...
