Or you could take the easy (cheap) way out:
<CFFUNCTION NAME="CreateAccount">
<CFARGUMENT NAME="lstKeyValuePairs" TYPE="String"/>
<CFSET var lstPair = "">
<CFSET var iMeetingID = "">
<CFSET var sAttending = "">
<CFLOOP LIST="#arguments.lstKeyValuePairs#" INDEX="lstPair">
<CFSET iMeetingID = ListGetAt(lstPair, 1, "=")>
<CFSET sAttending = ListGetAt(lstPair, 2, "=")>
</CFLOOP>
</CFFUNCTION>
--Then--
<CFINVOKE ... METHOD="CreateAccount">
<CFINVOKEARGUMENT NAME="lstKeyValuePairs"
VALUE="1=Bob,2=Sherry,3=Some Guy"/>
</CFINVOKE>
Especially if you're going to expose it as a WS (which it looks like you are
based on your designation of remote access), keeping input types simple
helps keep compatibility issues to a minimum.
The other alternative is, as Nathan suggested, looping through the arguments
collection. The only issue with that would be that if you don't know the
exact arguments ahead of time, WSDL/WS discovery doesn't always play nice.

Subject: RE: [CFCDev] Pass in "dynamic" arguments
The underlying issue, I suspect, is that CFARGUMENT is a compile-time
directive, so you can't define how many of them there will be at run-time.
Sounds like what you really want to pass is a struct of "attending" keyed
off the meetingID's you are passing in.
<cfargument name="meetingID" ...>
<cfargument name="attending" type="struct" required="false"
default="#structNew()#">
Alternatively, you could just loop from 2 to the structCount(arguments) and
grab each argument as you go, pairing it up to the MeetingID list -- that
way your end-developer can just pass in however many other arguments they
like.
On the other hand, it may be that what you really need to do is create a
different CFC that encapsulates this meeting/attending relationship and then
pass one of those as the value of your argument in createAccount.
