No, 

nAliases = nPages = nNodes + (nUsers * 2) + (nTags ^ nTags) + (nByModules)

(nByModules, for tagadelic, 2 * (nVocabularies ^ 25), or for image: nImages + 
nGalleries)

so, nAliases can be enourmous, humongous, redicoulous big, if this is to be 
used, we need to follow Moshes road of 'dynamic' aliases, i.e. aliases made 
on-the-fly. That is, what I wanted to do for tagadeli. 

So, not 
store /tagadelic/chunk/Foo,  /tagadelic/chunk/Foo+Bar  /tagadelic/chunk/Foo,Bar  /tagadelic/chunk/Foo+Faa 
and so on, but rather just match Foo, Faa, Bar against the db on call of that 
page.
