Hello.
is it possible to mysqldump specific tables from multiple databases in
a single run?
No.
database. I can not (even off hours) lock the entire database (main
one) long enough to do a full dump with locks so I see my options as:
You may write your own sql file in which you're locking the tables
which you need, selecting the data into outfiles and then unlocking
the tables.

all,

what I am trying to do is get replication slaves to a starting point
but am somewhat challenged by the nature of our architecture.
specifically, we have a large number of relatively-static (updated
only a few times/yr w/plenty of advance notice) tables which are
relatively big (~50GB among them) and a small number of tables that
are relatively small (~1GB among them) but are updated continuously
(several million DMLs/day). what I had done w/a single DB was
dump/load the static tables to a new slave then dump/load the dynamic
ones w/a --master-data which took ~1 min (acceptable off hours). that
got me to a point I could do a change master... then slave start and
be in business. I am now trying to merge in a small, secondary
application (only ~50K DMLs/day) which is currently in a separate
database. I can not (even off hours) lock the entire database (main
one) long enough to do a full dump with locks so I see my options as:
1. hope someone here knows how to do my original question
2. get architecture to sign off on consolidating tables into a single
database (in progress).
3. hope someone here know an approach I hadn't even thought of
(paradigm shifting w/o a clutch).
thoughts?
