ratcreature | looking for SGA fanfic with aliens... (interesting, not merely sex-obsessed ones *g*)

Somehow my google-fu and other search skills must be lacking, because I'd like to find certain kinds of SGA stories, but can't figure out an effective combination of google keywords or the right tags for searching on del.icio.us and such.

I'm looking for stories in which either an alien culture features prominently somehow, preferably if it's explored, but if one of the culture's aspects works as a plot device in an unusual way (and not just for the "aliens made them do it" genre, which is often indexed as such in link lists and tags and easier to find anyway) that's okay too, or stories in which they have first contact with non-human(oid) aliens, or stories doing both.

Examples for what I mean in the first category would be stories like (in no particular order):

The machinery of heaven by

flambeau
Your Cowboy Days Are Over by

samdonne (that one also has non-human aliens)
The Body Holographic by Leah and

springwoof
Duet by

blueraccoon
Planet Megalodon Wraith Defense Force by

pentapus
Eurydice Turns Left by

vee_fic
In the City of Seven Walls by

auburnnothenna (still a WIP, but with the added bonus of being slavefic)

and for the second category stories like:

Flying Blind by

minnow1212
Fellow Traveler by

ltlj
I guess Mostly Harmless by

astolat would also count, but I'm not looking for humor unless it's more plotty than "aliens made them do it".

Also I can't find the link to the most recent one I've read, which was on ff.net and not the most brilliantly written, but it had John being kept as children's pet by dinosaur people, so what's not to like? (ETA: I meant this one.)

BTW if you know of stories in which either John or Rodney is an alien, that would be great too. I mean stories like:

Angels in the Architecture by

docmichelle (John's a descended Ancient here, so maybe not technically alen, but it's still cool)
Just as required by

liviapenn
An Aesthetic Solitary Thing by

eliade (well-written wingfic + tentacles, how can that not be awesome?)
