You could open both at once, perhaps, using open() instead of backticks. How about this:
It doesn't read from them from the same time, but if the amount of data is smaller than 64 kilobytes, buffering should let the network communication happen simultaneously anyway. When you finish one, data may already be waiting for you on the second.
The chomp is to remove linefeeds and such, since unlike backticks open() doesn't do that for you. You just get a stream.
Running a handful of these at once is fine. Trying to run hundreds at once is not recommended.

face(1) User Commands face(1)NAME
face - executable for the Framed Access Command Environment Interface
SYNOPSIS
face [-i init_file] [-c command_file] [-a alias_file] [filename...]
DESCRIPTION
The Framed Access Command Environment Interface (FACE) presents your files and file folders on the screen through a system of menus and
forms if you are properly set up as a FACE user.
filename must follow the naming convention Menu.xxx for a menu, Form.xxx for a form, and Text.xxx for a text file, where xxx is any string
that conforms to the UNIX system file naming conventions. The Form and Menu Language Interpreter (FMLI) descriptor lifetime will be
ignored for all frames opened by argument to face. These frames have a lifetime of immortal by default. If filename is not specified on the
command line, the FACE Menu will be opened along with those objects specified by the
LOGINWIN environment variables. These variables are found in the user's .environ file.
OPTIONS
The following options are supported:
-a alias_file Alias file
-c command_file Command file
-i init_file Initial file
OPERANDS
The following operand is supported:
filename The full pathname of the file describing the object to be opened initially.
EXIT STATUS
The face command will return a non-zero exit value if the user is not properly set up as a FACE user.
FILES
$HOME/pref/.environ
