How 2 run same command across all open terminals

Hi folks. This has been bothering me for a while.

Among the 8 virtual desktops I'm using, I have 18 terminals open right now.

I change some of my user configuration (e.g. put a new alias into ~/.bashrc); but in order to use this new added alias, I have to source the config file:
Code:
. ~/.bashrc

That's all good, but the sourcing stays local to the current terminal. Is there a way to source my .bashrc on ALL open terminals, so that I can use it from any one of them?

I know I can echo into any terminal
Code:
echo Hello > /dev/pts/15

But is there a way to run a command like this?
Something like
Code:
$ echo . ~/.basrhc | /dev/pts/15
bash: /dev/pts/15: Permission denied
bash: echo: write error: Broken pipe

I'm running bash on CentOS box.
Thank you!

PTS_SOURCE(1)						       AFS Command Reference						     PTS_SOURCE(1)

NAME
pts_source - Read pts commands from a file SYNOPSIS
pts source [-file] <file name> [-cell] <cell name> [-noauth] [-localauth] [-force] pts so [-f] <file name> [-c] <cell name> [-n] [-l] [-f] DESCRIPTION
The pts source runs commands from a file as if they were typed in pts interactive mode. The command can be run from the command line or interactively. CAUTIONS
Prior to OpenAFS 1.4.5 and OpenAFS 1.5.23, the pts source command was only available on Unix or Linux and when OpenAFS was compiled with the supergroups option (disabled by default). As of OpenAFS 1.4.5 and 1.5.23, it is always available. OPTIONS
pts source takes the following options: -cell <cell name> Names the cell in which to run the command. For more details, see pts(1). -force Enables the command to continue executing as far as possible when errors or other problems occur, rather than halting execution at the first error. -help Prints the online help for this command. All other valid options are ignored. -localauth Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. Do not combine this flag with the -cell or -noauth options. For more details, see pts(1). -noauth Assigns the unprivileged identity anonymous to the issuer. For more details, see pts(1). OUTPUT
This command shows the output of each command in the file as if it were run normally. EXAMPLES
Here is an example of using pts source in a pts interactive session: % echo examine admin > /tmp/commands.txt % pts interactive pts> source /tmp/commands.txt Name: admin, id: 1, owner: system:administrators, creator: anonymous, membership: 2, flags: S----, group quota: 20. pts> quit % SEE ALSO
