In a more elaborate and tangential answer: no, and the only unique tech that helps a fleet is the Neural Net, which is found in Acient Ruins. It gives the highest experience level of any ship to all ships in a fleet, given that all participatin ships have the neural net component.

Other broad level bonus techs include religious WAR and DEATH shrines, an the Temoral EVENT PREDICTOR which effect all ships in a system. Oh yeah, and the Crystialine Shiled Boosting Thingy.

Some mods (though no popular mods, that I am aware of) included the ability to trade or capture racial techs. this cant be done in the stock game, but by making a component or facility granting techonology the postrequisite of some other fundamental racial technology, you can then trade or capture (via ship analysis) the second tier technology, even without the benefit of the preceding racial tech prerequisite.

and if that Last paragraph made no sense, you will just have to ask me to repeat it when im sober. or get someone more helpfull than myself to go over it. which isnt too hard, since most folks here are more helpfull than me.
