It's probably better to use:
[list prepend text]
as you don't need to concat the list to a single symbol,
[textextruded] can handle a list of symbols as well, also you don't
need any more externals then.

What problem are spaces? Regarding the first word being dropped: YOu
may want to read up a bit on how messages are handled in Pd, e.g.
Basically it's like this: Messages in Pd have two parts: A selector,
which is the "first word" from above, and the actual message data. The
selector is "float" for number messages, "symbol" for symbol messages,
"list" for list-messages and other words for "other" or meta-message.
As a special rule, a message without data is converted to a "bang"
message, and messages, whose data part start with a number, can omit
the "float" or "list" selector.
[netceceive] will spit out whatever message type you send to it. So if
you send "text pi pa po", it will output a "text" meta message, if you
send "list a b c", it's a list-message, if you send "hello world",
it's a meta message with selector "hello" i.e. a hello-message.
Now the tricky part that was wrong in your patch: dollar variables in
message boxes like [hello $1( take the replacement values from the
*data part* of incoming messages. The dollar variables ignore any
selectors. See attached patch for an example.
Note that some selectors actually make a message box do special
things, like the "set" or "addsemi" meta-messages.
