This seems most easily solved with an object-oriented DB.  If the DBs
are object-based and the objects present a consistent set of methods
(ways of communicating, basically) to the "outside world," it doesn't
matter what the internal implementations of the objects are on any
particular system or what presentation methods are used to display data
obtained from them.

For example, as long as any system can ask any other something like:

get.hardiness('vitis vinifera','F')

...and know that the queried system will return hardiness data in
degrees Farenheit for vitis vinifera (or a standardized "no data"
result), the data acquired can be dealt with however the querying site
chooses to.
